WebIn neuroscience, the visual P200 or P2 is a waveform component or feature of the event-related potential (ERP) measured at the human scalp. Like other potential changes measurable from the scalp, this effect is believed to reflect the post-synaptic activity of a specific neural process. WebHowever, it remains unclear whether excessive video game players (EVGPs) show altered behavioral and brain (event-related potentials; ERP) responses during cognitive tasks when compared to non-players (NPs). We measured ERP responses of EVGPs (n = 20) and NPs (n = 20) during a visual working memory (WM) task.
